When a cat roams, they are hunting, climbing, and patrolling territory. To keep them happy inside, you aren't just locking a door; you are becoming their Director of Entertainment. If the indoor environment is boring, they will spend their day meowing at the door or trying to bolt.
Before you start the transition, ensure your home is a sanctuary.
Microchip and Tags: Even though the goal is to stay inside, "escape artists" are common during the first few weeks. Make sure their info is up to date.
Window Security: Check that all screens are sturdy. A cat used to being outside might try to push through a flimsy screen if they see a bird.
Your cat needs to feel like they own the indoors.
Vertical Space: Cats feel safe when they are high up. Provide cat trees, wall shelves, or cleared-off tops of bookshelves.
The View: Give them a "Cat TV" by placing a perch next to a window. If you can put a bird feeder outside that window, even better.
The biggest reason cats want to go outside is to burn energy. You must replace the hunt.
Scheduled Sessions: Use wand toys to mimic the movement of birds or mice. Do this for 15 minutes twice a day.
The "Eat-Work" Method: Stop using standard bowls. Use puzzle feeders or hide small piles of kibble around the house so they have to "hunt" for their dinner.
